Comffit Tens Machine

Relief for sufferers of chronic pain

How is the Comffit TENS Machine different?

If you are looking for a reliable tens machine with strong treatment capabilities, the comffit tens machine is the ideal choice for these three simple reasons:

• 1) Effective Treatment of chronic (severe) pain

  The modulation mode featured in the unit is ideal for treating areas of chronic or severe pain. For example, pain caused by conditions such as rheumatoid arthritis, or a muscle tissue injury, back pain, shoulder pain, neck pain etc.
  • With the waveform constantly changing (using recommended modulation mode 'E'), the stimulus is smooth and comfortable. Importantly, this reduces the body's tolerance to the stimulus, therefore it is a more effective pain reliever.
  • The 'smooth' waveform also makes the machine much more comfortable to use.
  • The waveform is maintained even at high intensity, where it otherwise breaks down in poorly designed units.

• 2) Simple and easy to use

  • The large digital display makes reading and changing the settings easy, whilst the analogue knobs on the top of the unit makes it easier to adjust the intensity than pressing buttons.

• 3) Long term use is easy and won't cost you a lot of money

  All replacement leads, batteries, and electrodes are readily available.

  • Electrodes - We carry the highest quality replacement electrodes, and they can be purchased from this website. The electrodes are backed with a conductive gel. No extra gel is required.
  • Replacement leads - can be purchased separately at little cost
  • Batteries - No special hard-to-find batteries, just standard AA size (available in any supermarket or news agency)

 Features of the Comffit Tens Machine

• 1.Intensity protection (Safety)

  When the mode changes, the intensity will automatically go down to zero.

• 2.Remembers last settings

  When the unit is turned on, it will automatically return to the settings last used before the unit was switched off

• 3. Treatment Timer

  When the treatment timer is set, it will begin to count down in minutes. Once it reaches zero, the unit will automatically shut off

• 4. Auto Repeat

  When the pulse rate or pulse width is being adjusted, the auto-repeat function is available, when "PR+", "PR-", "Pw+", or "PW-" Key is held down for over 1 second, it will automatically increase or decrease 1 step per ¼ second

• 5. Precise Intensity Adjustment

  The two knobs on top of the unit adjust the intensity by turning clockwise or counter-clockwise. These knobs are accessible if you are wearing the unit on your trouser belt.

• 6. Switch Between Waveform Settings

  By pressing "PR-", key and "PW-" keys simultaneously, the two types of waveforms can be changed.

• 7. Lock the Settings in Place

  By pressing "timer key" for 2 seconds the unit will be locked or unlocked in toggle. While the unit is locked, the parameters cannot be adjusted except for the timer and intensity. Pressing the ON/OFF key will not change the locked/unlocked status.

• 8. Low Battery Indicator

  When the batteries are low, a flashing battery symbol in 2Hz will indicate that the batteries should be replaced.

• 9. Battery Saver

  Automatic shut off. When the unit intensity levels are 0 on both channels, and it has not been in use for 5 minutes, the unit will shut off automatically.
